摘要: 背景与目的: 探讨中药方剂1号对人胃癌细胞SGC-7901体外生长及细胞周期的影响。 材料与方法: 四甲基偶氮唑蓝 (3-[4,5-dimethylthiazol-2-y1]-2,5 dipheny1 tetrazolium bromide,MTT)还原法检测中药方剂1号对SGC-7901细胞增殖的影响;流式细胞仪检测细胞周期时相分布。 结果: 中药方剂1号生药能抑制SGC-7901的增殖。在实验浓度范围内,随着剂量的增加,抑制作用更加明显;同一剂量下,72h内药物作用时间越长,抑制作用越明显。中药方剂1号作用48 h后,SGC-7901细胞的G0/G1期和S期的细胞减少,G2+M期的细胞增多。 结论: 中药方剂1号能够抑制人胃癌细胞SGC-7901的体外增殖,其作用机制可能与干扰细胞周期有关。

Abstract: BACKGROUND&AIM: To investigate the effects of Prescription of Traditional Chinese Medicine-1(PTCM-1) on the proliferation and the cell cycle change arrest of human gastric carcinoma cell line SGC-7901 in vitro. MATERIAL AND METHODS: The proliferation of SGC-7901 cells was measured by 3-[4,5-dimethylthiazol-2-y1]-2,5 dipheny1 tetrazolium bromide(MTT) colorimetric assay. The cell cycle phase was analysised by flow cytometry. RESULTS: PTCM-1 inhibited the proliferation of SGC-7901 cells in dose-dependent manner and in time-dependent manner from 0 h to 72 h. After treated by PTCM-1 for 48 h, the SGC-7901 cells were accumulated in G2+M phase in the cell cycle, and the ratio of cells in G0/G1, S phase was decreased. CONCLUSION: PTCM-1 can inhibit proliferation of SGC-7901 cells. It interferences into the cell cycle may be one of mechinism of its antitumor activity.
